The path will provide level service access to the new £102,000 hall extension, funded by Stroud Town Council with a generous contribution from Biffa Award.
The extension will be used as a backstage green room and equipment store.
Rather than using more tarmac, the “floating” pathway will be built of green oak.
“We wanted the path to be more in keeping with the nature of the gardens and the green values of the council,” said town councillor Steve Hurrell, chair of the Lansdown Hall Working Group.
Designed by architect Nick Hurst of Minchinhampton-based Apple Design the new path will also mean that the roots of adjacent trees in Bank Gardens will not be disturbed.
Other parts of the Biffa Award have already paid for the inner lobby to the Gallery and the air-to-water heat exchangers, both installed in the Autumn. The hall has already received funding from the Garfield Weston Fund.
The Biffa grant supports making the building a better environment for all who work in it, as well as being more energy efficient.
Work on the pathway should be completed by July.
The Town Council bought Lansdown Hall in 2010 to save it from closure. It is run by a charitable trust and provides a community space for the town.
A programme of major repairs and refurbishment is ongoing. The hall remains open during the work, for information on upcoming events please visit www.lansdownhall.org.
